Myelin-gene regulatory factor (MYRF) is a membrane-bound transcription factors, which is responsible for the differentiation of oligodendrocytes and myelination of central nervous system. Followed by a self-cleavage by the intramolecular chaperone auto-processing (ICA) domain, DNA-binding domain (DBD) of MYRF is released from the endoplasmic reticulum (ER) and was then translocated to the nucleus to regulate gene expression. In present work, we have solved the crystal structure of the human MYRF-DBD to 1.85-A resolution. It exhibits a typical s-type Ig-fold and packs as symmetric trimeric form in the crystal via hydrogen-bond networks in three regions. Accordingly, we identified a couple of key residues on MYRF-DBD, which might play important roles in DNA-binding, in particular Arg521 on its C-terminal tail. The R521A mutant of DBD showed only 17% affinity to dsDNA targets compared to wild-type DBD. Then we built a plausible protein-DNA binding model of MYRF-DBD, which will help to elucidate its mechanism in DNA-binding and transcriptional regulation.
